Do Marvel Comics' just-released September 2022 solicitations look just a bit familiar to you? As in, are you feeling just a bit of deja-vu about some of the covers and solicit text included in Marvel's September 2022 solicits?

Don't worry, you're not caught in a time warp.

Marvel Comics September 2022 solicitations actually include a significant number of titles that have been resolicited from their originally announced August 2022 release dates - 31 titles total - so yeah, you've seen some of the books in the September solicits before.

Here's a list of all the titles Marvel Comics has resolicited from August, organized by their new September 2022 release dates:
